sum the all values from an array

var numbers = [3, 5, 7, 2];
var sum = numbers.reduce((x, y) => x + y);
console.log(sum); // returns 17

// other way

x = sumAll(1, 123, 500, 115, 44, 88);

function sumAll() {
  var i;
  var sum = 0;
  for (i = 0; i < arguments.length; i++) {
    sum += arguments[i];
  }
  return sum;
}

sum all values of an array

 function array(arr){
   var sum = 0;
   for (var i = 0; i< arr.length; i++){
    sum += arr[i];
   }
   console.log(sum);
 }
 array([5, 1, 3, 3])

sum of array of number

const sum = [1, 2, 3].reduce((partialSum, a) => partialSum + a, 0);
console.log(sum); // 6

how to find sum of array

//C++
int arr[5]={1,2,3,4,5};
int sum=0;
for(int i=0; i<5; i++){sum+=arr[i];}
cout<<sum;

sum of array
